Keenval Trojan/Spyware Problems HIJACK LOG FILE

Heres my latest Hijack log file. I recently looked over a tutorial for analysing them, and I tried doing it myself due to my forum I usually post my log files was inactive. (The Board Moderators who did the logs were away on vacation) I have 3 trojan Keenval viruses on my computer but my AV wont get rid of them, and I have a spyware problem that goes to a search engine whenever I open up IE. And it wants to go to the same search pagewhen i go my yahoo mail, so I have to continoually press Stop to avoid it. Please help me, I really need it. >.<
